I burn a lot of midnight oil so I'll let you wake up to this.

Your girls will be just fine, there is absolutely nothing wrong with them, that I can see with the pics you have up. Every ounce of data that I have researched leads me to believe that presence of seeds will not hurt the overall potency of the final product. That being said, since the stuff is usually consumed by weight, you are only losing on yield of your final product. If the plant is using engery to produce seeds, it won't be using that energy to produce buds, and they will factor into your final weight.

In a perfect world, your plant would not have been pollinated, and would not have produced any seeds. One of cannabis' reactions to there being zero pollen is creating more pistils and flower mass to catch pollen, so in theory even if there is no pollen to be had, the plant will keep amassing material to try to catch whatever stray may come by. These are the reasons that most growers (unless they are breeding) throw away the males.

Don't stress over being a little rough with your girls. They are built to withstand abuse, albeit within certain parameters. I pinch and smell my buds all the time, I love to follow the smell as it changes. I think that is one of the rewards of the growing process. The worst you are going to do pinching your nugs, lol, is bruise a few of the aforementioned trichromes. Nothing to be concerned with. I'll check back in with you in the morning and see what we can find out.
